Estas quemaduras de la piel son causadas por la luz ultravioleta (UV) del Sol. Las quemaduras graves no s\u00f3lo son dolorosas sino que tambi\u00e9n pueden causar c\u00e1ncer de piel.<\/p>\n<\/div>\n<p>Por fortuna, casi toda la radiaci\u00f3n ultravioleta nociva es absorbida por una capa gaseosa de ozono situada entre 20 y 50 km sobre la Tierra. Sin embargo, el ozono es una forma de ox\u00edgeno que puede ser destruida f\u00e1cilmente por ciertas sustancias qu\u00edmicas fabricadas por el hombre.<\/p>\n<p>En 1987, los principales pa\u00edses industrializados acordaron la eliminaci\u00f3n progresiva de dichos qu\u00edmicos. A pesar de ello, los sat\u00e9lites han demostrado que la capa de ozono ha seguido reduci\u00e9ndose sobre la Ant\u00e1rtida. El agujero de ozono alcanz\u00f3 un tama\u00f1o r\u00e9cord en 2000, cuando abarc\u00f3 casi 30 millones de kil\u00f3metros cuadrados, que es el tama\u00f1o aproximado de Norteam\u00e9rica. En 2006, la atm\u00f3sfera perdi\u00f3 una cantidad a\u00fan mayor de ozono, a pesar de que el agujero era ligeramente m\u00e1s peque\u00f1o.<\/p>\n<p>Tambi\u00e9n han aparecido agujeros de ozono m\u00e1s peque\u00f1os sobre el \u00c1rtico. Dichos agujeros permiten el paso de mayor cantidad de luz ultravioleta hacia las zonas densamente pobladas de Europa.<\/p>\n<figure class=\"wp-block-image size-natural\" data-width=\"400\" data-credit=\"ESA\/KNMI\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2004\/09\/Ozone_hole_forecast_from_today_to_9_September2\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2004\/09\/ozone_hole_forecast_from_today_to_9_september2\/17878144-2-eng-GB\/Ozone_hole_forecast_from_today_to_9_September.jpg\" alt=\"Ozone hole forecast from today to 9 September\"><figcaption>Previsi\u00f3n del agujero de la capa de ozono desde hoy hasta el 9 de septiembre<\/figcaption><\/figure>\n<p>Los sat\u00e9lites de la ESA, como el MetOp y el Envisat, desempe\u00f1an un papel fundamental en los estudios sobre el agujero de ozono.
